What is a BAB breaker?
Eaton’s bolt-on miniature circuit breakers (Quicklag) provide superior protection in panelboards, and offer easy installation. They are also switching duty rated for 120 VAC fluorescent light applications, and UL 489 listed. All products 15–100A are HACR rated.
What is a CH style breaker?
Eaton’s residential CH circuit breakers provide premium overload protection. The Type CH circuit breakers trip to the OFF position, eliminating nuisance callbacks. The CHF family also includes a trip flag to differentiate between a trip and the breaker being turned off.
What are the two types of Cutler Hammer breakers?
Different circuit breaker types that are low voltage include molded case circuit breakers (MCCB) and miniature circuit breakers (MCB).
What circuit breakers are compatible with Westinghouse?
Answer: The Eaton Cutler-Hammer 30 Amp Double-Pole Type BR Replacement Circuit Breaker is compatible with Westinghouse, Challenger and Bryant load centers and has a maximum load of 240-Volt.
What are common trip breakers?
Two pole breakers are common trip. Two single pole breakers with a handle tie are not common trip. Breakers are designed to trip even if the handles are restrained for some reason. They even make a clip to lock a breaker handle in the “on” position for critical equipment that can’t be turned off.
What’s the difference between BR and Ch breakers?
Eaton’s Type CH circuit breakers protect the wires in your home from overheating (referred to as an overload) and fault currents (referred to as short circuits). BR breakers are 1″ in Width. BR breakers are black, with black handles (In most cases. BR breakers carry a 10 Year Warranty.
What is the difference between Type BR and BD breakers?
Type BR tandem breakers are non-class CTL, and are labeled “For replacement use only” They will fit anywhere in the panel, and using them can exceed the number of circuits that a panel was designed and listed to accept. The BR type are much more expensive than the BD type, BTW.
Are Westinghouse and Square D breakers interchangeable?

What kind of circuit breakers are HACR rated?
All products 15–100A are HACR rated. Select from one-, two-, or three-pole designs. Flexible power feed connection (wire size and position) offers product uniformity as well as ease of installation.
When did the need for circuit breakers come about?
The need for molded-case circuit breakers came about in 1918 when numerous applications for electrical motors resulted in a demand for a device that would ensure safe operation and, at the same time, protect electrical circuits.
What does NEC stand for in circuit breakers?
The NEC®describes them as “. . . a device designed to open and close a circuit by non-automatic means, and to open the circuit automatically on a predetermined overload of current, without injury to itself when properly applied within its rating.”
